OSTEOARTHRITIS
Short-term efficacy of physical interventions in osteoarthritic knee pain. A systematic review and meta-analysis of randomised placebo-controlled trials
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2013;1(11):187 BMC Musculoskelet Disord. 2007 Jun 22;8:51This systematic review with meta-analysis for 36 randomized placebo-controlled trials looked at the efficacy of physical modalities (transcutaneous electrical stimulation - TENS, electro-acupuncture - EA, pulsed electromagnetic fields - PEMF, ultrasound - US, and low level laser treatment - LLLT) in patients with knee osteoarthritis (OA) pain within 1-4 weeks and at follow-up at 1-12 weeks after the treatment. The 36 RCTs identified had 2434 patients with a mean age of 65.1 years (1391 patients received active treatment). Results indicated that the optimal doses of TENS, EA and LLLT appear to offer short-term pain relief for knee OA.

Fragility Indexは、重要な所見の解釈を助けるツールで、結果の強さの尺度を提供します。Fragility Indexは、その所見が有意でなくなるために、二項対立の結果に追加する必要がある連続した事象の数を表します。数値が小さいほど弱い所見を表し、数値が大きいほど強い所見を表します。
なぜ今この研究が必要なのですか？
The most common type of osteoarthritis (OA) is osteoarthritis of the knee. It is associated with pain and inflammation, loss of function, impaired muscle stabilization and reduced range of motion. There is uncertainty on the efficacy of non-pharmacological physical modalities on knee osteoarthritis pain. This systematic review and meta-analysis was needed to examine the short-term effects of physical modalities on OA pain.
主な研究課題は何ですか？
Does the use of physical modalities (transcutaneous electrical stimulation, electro-acupuncture, pulsed electromagnetic fields, ultrasound, low level laser treatment) offer clinically significant short-term pain relief for individuals with knee osteoarthritis?
重要な知見は？
- Clinically relevant pain-relieving effects were seen with the use of transcutaneous electrical nerve stimulation (TENS) (18.8 mm [95% CI: 9.6 to 28.1]) (n=414), electro-acupuncture (EA) (21.9 mm [95%CI: 17.3 to 26.5]) (n=73) and low level laser therapy (LLLT) (17.7 mm [95% CI: 8.1 to 27.3]) (n=343) measured by VAS compared to the placebo.
- When a subgroup analysis of trials was performed with assumed optimal doses, an increase in efficacy was seen. TENS had an increase to 22.2 mm [95%CI: 18.1 to 26.3], LTT had an increase to 24.2 mm [95%CI: 17.3 to 31.3] on VAS.
- A small reduction in pain was seen when pulsed electromagnetic fields were used measured by VAS. (6.9 mm [95%CI: 2.2 to 11.6]) (n=487)
- No statistically significant reduction in short-term pain was seen over the placebo at 4 weeks from the treatments of manual acupuncture, static magnets, and ultrasound therapies (p>0.05).
- There was minimal follow-up data up to 12 weeks, but the outcome effects of TENS, EA, and LLLT seemed to persist for at least 4 weeks after the treatments ended.
- The mean methodological quality scores over all the included trials was 3.8 out of a score of 5 on the Jadad scale.
最も覚えておくべきことは？
The use of transcutaneous electrical nerve stimulation (TENS), electro-acupuncture (EA), and low level laser therapy (LLLT) at optimum doses in an intensive 2-4 week treatment program appeared to produce clinically relevant short-term pain relief in patients with knee osteoarthritis.
それが私の患者ケアにどのように影響するか？
Patients may find short-term pain relief from knee OA when they undergo a regimen of TENS, EA or LLLT. These physical therapies also appear to be a safe method of pain management for knee OA as no serious adverse events were reported in the RCTs reviewed. Based on this study, MA, PEMF, US and SM can not be recommended due to lack of efficacy on short-term pain relief for knee OA. Further high quality evidence is needed to support these findings.
